I have downloaded the Dutch language course from Rosetta Stone.
Original file is 3 .iso files. Have opened these with daemon tools, every iso file is now subdivided into 4 folders;
data contains a whole load of rsd files
documentation contains adobe files
language contains 1 text file
speech contains 1 rsd file.
I somehow need to put all this together to make the course work but I genuinely don't have a clue where to start.
